A car is driving 2 laps around a circular, 1 mile track. If the first lap was completed at 30 MPH, at what speed would the car need to drive the second lap to average 60 MPH.

Paul Z.

Answer:

It is impossible. In order to average 60 MPH, the car would need to complete both laps in 2 minutes. Since the car completed the first lap in 2 minutes, it does not matter how fast the car completes the second lap since the 2 minute requirement has already lapsed.
